1 Claim. (Cl. 242-1102) This invention relates to improvements in windngor reeling devices and is particularly directed to an improved and novelwinding spool for use in winding or coiling wire and similar materials.i

A primary object of this invention is to provide a winding spool, ontoand from which coled wire and the like material may be moved in coilform.

Another primary object of this invention is to provide a winding spoolwhich can be easily and readily attached to -a power means', such as thepulley on the power takeoff of a tractor, for the purpose of windingwire into coils or reels and for unwindng coiled or reeled wire and thelike materials.

Another important object of this invention is to provide a windng spool,which includes a detachable end wall on one end of a mandrel, which isradially inwardly collapsible so that the coled wire may be passed overthe end of the mandrel, associated with the detachable end wall, whenthe mandrel is' collapsed.

Another important object of this invention is to provide an end wall,which is fiiedly associated with one end of the mandrel and whichsupports the mandrel in its winding position 'and in its collapsedposition, and which carries a drive means for rotating the spool to windor unwind the wire.

Another object of this invention is to provide a device for winding orcoiling wire and the like flexible material in a manner so as to obviatethe need for using a core and so that the coiled wire may -be easilystored in compact bundles and may be easily and quickly replaced on thespool for unwinding purposes.

The foregoing and ancillary objects are obtained by this invention, thepreferred embodiment of which is set forth in the following descriptionand llustrated in the accompanying drawings, wherein:

Fig. 1 is a longitudinal, vertical, sectional view of the winding spooland is taken substantially along line l -l of Fig. 2, with parts brokenaway and others depicted in section.

Fig. 2 is an end elevational View of the wnding spool;

Fig. 3 is a front elevational view thereof, showing the same in itswinding or unwinding position, and,

Fig. 4 is an elevational View, similar to Fig. 3, with the winding spoolshown in its collapsed position.

While one embodiment of the invention is illustrated in the abovereferred to drawings, it is to be understood that they are merely forthe purpose of illustration and that various changes in Construction maybe resorted to in the course of manufacture in order that the inventionmay be utilized to the best advantage according to circumstances whichmay arise, without in any manner departing from the spirit and intentionof the device, which is to be limited only in accordance with theappended claim. And while there is stated the primary field of utilityof the invention, it remains obvious' that it may be employed in anyother capacity Wherein it may be found applicable.

Referring now more particularly to the accompanyice ing drawings thenumeral 10 generally designates the winding spool in its entirety and 12indicates a mounting or supporting frame, which supports the windingspool. A pillow block 14 is mounted on the frame 12 and secured theretoby *bolts 16. A driving shaft 18 is rotatably oarried by the pillowblock and extends laterally therefrom in opposite directions. One end ofthe shaft is provided with -a pulley or the like (not shown) forattachment to a power means, such as the pulley on the power take-off ofa tractor or the like machine. The opposite end of the shaft 18, asshown in Fig. 1, is threaded into the threaded socket 2& of a tubularshaft or sleeve 22. The parts are preferably threaded together for easydetachment but the connection 'may be made by weldng or any othersuitable means. The socket 20 is formed in one end of the sleeve and isof a greater diameter than the axial `bore 24 in the sleeve, the socketbeing counter-bored and providing a stop shoulder to limit thepnojection of the shaft 18 into the sleeve. Suitable means, such aswashers 26 and 28 are provided on opposite sides of the pillow block andcircumposed on the s'haft to prevent axial movement of the shaft withinthe pillow block.

The spool 10 includes an end wall or stationary flange 30, which isdisposed adjacent to the frame 12 and which is provided with'a hub 32,through which the shaft 13 extends. The hub 32 is welded or otherwisesuitably secured on the shaft 18 so as to be rotated therewith. Forexample, a setscrew 34 is radially carried by the hub and socketed inthe shaft for -securing the ange on the shaft.

A mandrel generally designated by the numeral 36, is carried by theinner side of the flange 30 and is composed of a number of complementalsections or segments, which may be two or more in number. Three of suchsegments, 38, 40 and 42 are illustrated. Each of the segments istransversely arcuate and the segments are coextentive in length andwidth and are arranged in a circular formaton so as to provide thecylindrical shape of the mand rel. One of the segments, which isindicated by the numeral 4-2 is stationary, being integral with or fixedto the flange 3i3, as by welding or the like, so that it projects, in afixed position, laterally from the inner side of the ange, while theother sections 38 and 40 are hingedly attached to the inner side of theange 30 with hinges i i and 46.

The sleeve 22 is supported by the fixed section or segment 42, by meansof a radially offset projection 43 on the sleeve, which projection issuitably attached, by welding or the like, to the inner face of themandrel section 42. The mandrel section 38 also supports bearing arm 50,which extends radially inwardly therefrom.

A guide rod 52 is supported by the heating arm St? and s slidablydisposed therein and s telescopically and slideably arranged in the bore24 of the sleeve 22,. The guide rod 52 is provided at its outer end withradially projecting apertured ears 54 and with 'a similar ear se. Theears 54 'lie in the same circle around the guide rod, while the ear 56is disposed outwardly therefrom, and the ears are spaced apartcircumferentially on the guide rod, in accordance with the circlespacing of the mandrel sections. The ears 54 are attached to aperturedears or lugs 58, which are provided on the inner sides of the sections38 and 40, by means of links 60. The links 69 provide a pivotal linkagemeans, whereby upon inwardly sliding movement of the guide red 52 thesections 38 and 40 are swung radially inwardly about their hingedconnections to the fixedly located flange 30. Upon out ward slidingmovement of the guide rod 52, the sections are moved radially outwardlyand restored to their normal positions, shown in Figs. 2 and 3. Thus,the links translate the axial movement of the guide rod into radi allyswinging movement of the mandrel sections 38 an Means is provided forsliding the, guide rod 52 in the bearing arm and the sleeve 22 andpreferably includes an angular bell crank or handle 61, which ispivotally sup,

ported' on the fixed mandrel section 42 by means of a end. The hanclle61 is pivotally attached by a link 6 6 to an ear 56 on the rod 52.

A detachable end wall or removable flange 68 is-provided to complementthe fiange 30 and function as a guide flange therewith for the mandrel36. The flange 68 is provided with a center hub m that is circumposedabout the outer end of the mandreland is detachably secured to the fixedmandrel section 42' by a stud 72. The stud 72' secures the flange 68 inplace and is easily removed to permit a speedy andfeasy removal of theflange 68, when it is desired to Collapse the mandrel.

operation When the winding spool is used for Winding and unwinding wireonto and froma coiled form (it` being understood that other exiblematerials than wire may be handled by the winding spool), the mandrel'segments 38 and 40 are' in their outer' positions, complementng thefixed segment 42 in providing the cylindrical shape of the mandrel. Themandrel segments 38 and 40' are maintained in" such positions due to thefact that the ears 54 ands58 are slightly over center and thereforeforcng an action outwardly on the shaft 52 against the handle 61 andbecause, medially of the handle 61 the angular projection 74 thereofabuts the fixed mandrel segment 42. The fiange 68 is Secured in placeon' the outer end of the mandrel and the winding spool isfin theposition,` shown in Fig. 3. In such position, the 'entire spoolwill berotated by the shaft 18, either in a' clockwise or counter-clockwisedirection, depending' upon whether the wire is being wound thereon' orunwound' therefrom.

When the desired amount of wire has been coiled" on the spool, thehandle 61 is swung upwardly and inwardly to slide the guide rod 52 intothe sleeve 22 and thereby cause the mandrel segments 38 and 40 to swinginwardly efiectng an inward radial Collapse of the' mane drel. wire slidaxially off the mandrel.

When a wire col is to be unwound and distributed, a'

reverse action takes place., The wire coil is placed' on The fiange 68is then removed and. the coiled From the foregoing specification, itwill become apparent that the invention disclosed will adequatelyaccomplish the functions for which it has been designed andin anecouomical manner, and that its Simplicity, accuracy, and ease ofoperation are such as to provide a relatively inexpensive device,considerirg what it will accomplish, and that it will find an importantplace in the art to which it appertains When once placed on the market.

lt is thought that persons skilled in the art to which the inventonrelates will be able to obtain a clear unclerstanding of the inventionafter considering` the description in connection with the drawings.Therefore a more lengthy description is regarded as-unnecessary.

Changes in shape, size and rearrangement of details and parts such ascome within the purview of the invention claimed may be resorted to inactual practice, if desred.
